Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I bought my Chevy traverse car in June 2021 with 0 miles. On 12/25/2023 the alternator went out. I know there any many people who are having this same problem when the car reaches 40k miles. This is not fare to us bc we now have to pay 1700 in repairs. If the alternator goes out when driving, your car will stall and stop and you can end up in a sudden crash. This should not be happening at 40,000 miles.”
NHTSA complaint #11563091, filed 2024-01“I have a 2021 Chevy Traverse LT. The stereo touch screen keeps completely freezing. We've brought it to the dealer who told us it was working fine. Its frozen twice. Once we had to pull the fuse out to reset it for it to work. Vehicle has a rattle at startup and suspension squeaks. Captain seats almost seem loose, they rattle at times. The brakes are horrible, they squeak all the time. …”
NHTSA complaint #11449517, filed 2022-01“In the first 51,000 on my vehicle I have had 3 issues with the emissions system which has a negative impact on the environment and would prevent my vehicle from passing state inspection. GM covered the first 2 under warranty, but I now have a leak in my muffler which seems that it could be related to other issues involving brackets on the exhaust pipes breaking. This is widely reported by other Traverse owners yet GM has not extended the warranty to cover this.”
NHTSA complaint #11696537, filed 2025-10“Around 8-19-24 I started noticing liquid on my garage floor. It had a slight oil consistency to it. I brought it in to a local auto shop who inspected it and confirmed the radiator was leaking randomly. There was no visible damage to it and no reason it should have started leaking when only 3.5 years old and only had 53k miles on it. No indicators of any kind prior to the leaking starting either. It started leaking a little bit one day and each day it started leaking progressively more.”
NHTSA complaint #11636361, filed 2025-01“a few days after purchasing vehicle a rotten egg smell started coming out of AC. took to dealership twice and they cant find the problem and since the smell comes and goes we were informed that this happens because is a brand new vehicle. But i'm d one getting terrible headaches when that smell comes out of no where. Last time it happened i was ready to go to emergency room it was so bad i had to open up d windows to get some air.”
